My screen on my iphone 2g will not work. I cracked the screen and it still worked. I ordered a new outer screen on ebay and tried to replace it. While getting the old cracked screen off the touchscreen i gouged the screen a little bit. Is there any other reason besides this that my screen would not be working? Could I have hooked something up wrong? Also, when taking out my battery I punctured it a little bit, and a little cloud of smoke came out. It still charges and seems to hold a charge fine. Should I be worried at all?
